Altronix MAXIMAL33V 16-Output Access Power Controller

Altronix MAXIMAL33V Access Power Controller

Overview

The Altronix MAXIMAL33V is a comprehensive access control power distribution and battery backup system engineered for security installations requiring reliable 12/24VDC output with integrated relay switching and charger functionality. Housed in a BC800 steel enclosure rated for 220VAC input, the MAXIMAL33V delivers dual independent power supplies at 6 amps each, supporting medium to large-scale access control deployments including door locks, magnetic locks, request-to-exit sensors, and auxiliary security devices. The integrated 16 fused relay outputs provide flexible load switching and device protection, while built-in battery charging capability maintains system integrity during AC power loss.

Key Features

• Dual Power Supplies: 12VDC @ 6A and 24VDC @ 6A independent channels for flexible device voltage requirements
• 16 Fused Relay Outputs: Distributes power to access control devices with individual circuit protection
• 220VAC Input Voltage: Accepts standard mains AC input for reliable primary power conversion
• Integrated Battery Charger: Built-in charger supports 12/24VDC battery systems for uninterrupted backup power during mains failure
• BC800 Steel Enclosure: Durable, compact form factor suitable for wall or panel mounting in security equipment rooms
• 16 Output Control: Enables independent switching of multiple access control zones and auxiliary loads
• Power Supply Redundancy: Separate 12V and 24V channels allow mixed-voltage device architectures without crosstalk
• Circuit-Level Protection: Fused relay outputs protect downstream devices from short circuits and overload conditions

Integration & Compatibility

The MAXIMAL33V integrates into access control systems requiring distributed power management across multiple security zones. The dual voltage architecture supports heterogeneous device deployments—12VDC electromagnetic locks and 24VDC request-to-exit buttons can operate simultaneously from the same controller. Relay outputs accommodate door holders, alarm notification devices, and secondary system triggers. The integrated charger functions with standard lead-acid or sealed battery packs rated 12/24VDC, enabling system operation during AC mains interruptions. Installation in the BC800 enclosure provides a self-contained power distribution point, minimizing field wiring complexity and centralizing circuit protection.

Karl Wilson

Having evaluated the Altronix MAXIMAL33V during planning for a multi-tenant access control retrofit, I found this unit well-suited for deployments requiring centralized power distribution with battery backup across multiple access points. The dual 6-amp channels accommodate typical electromagnetic lock and control device loads without over-provisioning or voltage conflicts.

Technical Highlights:

• Dual Independent Outputs: The 12VDC and 24VDC channels operate independently, enabling single-unit support for mixed-voltage device architectures common in modular access control installations.
• 16-Output Relay Distribution: Fused outputs provide granular control and per-circuit protection, reducing troubleshooting time and preventing cascading failures across dependent devices.
• Integrated Charger Function: Built-in battery charging eliminates the need for separate UPS hardware, streamlining the power architecture and reducing enclosure footprint.

Deployment Considerations:

• Verify battery specification (12 or 24VDC rating) matches your intended backup duration and load profile before installation.
• The BC800 enclosure is compact; plan cable management and fuse accessibility during raceway layout to facilitate future maintenance.
• Confirm downstream device current draw does not exceed 6A per rail; excess load will trip per-channel protection, requiring load rebalancing across outputs.

The MAXIMAL33V is a practical, cost-effective solution for access control power centralization in medium-scale installations. Its fused relay architecture and integrated charger reduce component count and simplify system commissioning.
